Ginkgo is a gymnosperm that has male and female organs on separate trees. The male trees are used for taking cuttings more often than the female trees because the male trees grow upright and have smaller crowns than the female trees. Because of this favouritism, ginkgo trees have been listed on the endangered species lists because female trees are being outnumbered by male trees. A slow-growing tree, ginkgo takes about 10 years to reach 20 feet tall. The best time to take ginkgo cuttings is from May through July from young wood.
Pour seed starting medium into a medium-sized biodegradable pot. Moisten the medium with water.
Measure about 6 inches down from the tip of a new-growth branch. Cut the branch at a 90-degree angle with a pair of sharp pruners.
Stick the cut end of the cutting about an inch into the seed starting medium.
Dig a hole outdoors that is large enough to set the pot in. Set the pot down into the hole. Water the cutting until the soil is moist.
Create a frame around the pot and cutting. Insert a wooden stick that is taller than the cutting on both sides of the cutting. Place a large clear plastic bag over the top of the sticks and cutting. Keep the soil moist around the cutting to promote root growth.
Allow about two years for the cutting to grow. The cutting will root in the spring.
Not all cuttings will develop roots.
